Create a new acute triangle and label the vertices. Create a blank sketchpad by selecting “File” from the top menu. Check your hypothesis using the other two sides. What do you think is the relationship between the segment from the midpoint to the centroid and the vertex and the centroid. The intersections of the medians is called the centroid. What is the calculation of the ratio of the two parts of the median? 1-e. Click on the “GF = …” box, then the division sign, ÷, and finally click on the “AG = …” box. We are going to calculate the ratio of the two parts of the median AF. From the top menu select “Measure” and “Calculate” from the drop-down menu. Select the intersection G and the midpoint F and calculate the distance between the points. On the upper left part of the white field should be the box “AG = …” 4. From the top menu select “Measure” and “Distance” from the drop-down menu. Select the vertex A and the intersection G. Label the intersection of the medians, “G” 2. Does the intersection ever move out of the interior of the triangle? If you make different shaped triangles do the medians still intersect? 1-c. What do you notice about the three medians? 1-b. Copy your Triangle with the medians to you Word document. AC should have midpoint E and BC should have midpoint F. Construct the other two medians by repeating steps 1-4. To draw the median, select the midpoint, D, and the opposite vertex, C. In the top menu click on “Construct” and choose “Midpoint” from the drop-down menu. Save the word document as “lastname_geo1” into your documents. Create and paste to a word document: 1) your original triangle 2) an acute triangle and 3) an obtuse triangle. Once a triangle is drawn you can then change its look by clicking on a vertex and while holding down the mouse, move the vertex around the field. This should paste the triangle to a new word document.Ħ. Once open go to the top menu, select “Edit” and from the drow-down list select “Paste.” Or hold down Ctrl+V. To copy the selected objects go to the top menu, select “Edit” and from the drowdown list select “Copy.” Or hold down Ctrl+C. To select all objects you can also hold down the Ctrl+A keys. To select objects to copy either select each one at a time or left click into the top left corner, hold down the left click, and drag to the bottom right. If not, double click onto a label and a menu should appear that you can modify the labeling.Ĭopying diagrams to MS Word 1. The three vertices should be labeled “A”,”B”, and “C” in the order that you selected them in. From the top menu select “Display” and from the drop-down menu select “Show Labels.” 3. Once a triangle is drawn you can then change its look by clicking on a vertex and while holding down the mouse move the vertex around the field. Click on another set of points and draw the segment and the same for the last two points. Click into the white field to deselect the segment. A segment should have been drawn connecting the two points and will be highlighted. Select the option “Segment” from the list. From the top menu select “Construct” to get a drop-down menu. Click on a second point to highlight another point. The last point you created should be highlighted. Create two more spaced out in the field for a total of three points. In the white field click with the mouse to create a point. We will be using both.Ĭreating a triangle 1. There should be a blank white screen with commands on the top: and a tool bar to the left of the screen. Introduction After signing on to the computer, open programs and select.
